I bought the very first iPad with unlimited data plan from AT&T but have upgraded twice to iPad minis. I currently use the iPad mini 3 with unlimited data. I hope that Apple releases a pro version of the mini so that I can use the apple pen with it. But I get the feeling that Apple is going to phase the mini out. It's just not getting the love it deserves. Too bad. Because for me, the mini is the perfect sized iPad for travel. Perhaps Apple feels it's too close in size to the iphone Plus? I dunno. I don't think it is, but that is what I am hearing. Again, I hope they release a pro version, cause if they don't, I will have to say goodbye to the mini and be forced to buy the 9.7" or the rumored 10.5" bezel-less iPad pro.
